| Abstract(in English) | To achieve diversity with a single antenna, Fractional Sampling (FS) has been proposed. The imaging component of a desired signal is necessary to be transmitted by increasing baseband filter bandwidth. This paper proposes and evaluates the system in which the imaging component is transmitted on the adjacent channel of the desired signal. The adjacent channel interference is canceled by the precoding generated based on the channel state information (CSI) of all the terminals. In this paper, the performance with the perfect feedback and the limited feedback are evaluated. Numerical results through computer simulation show that, the proposed scheme with a 6 bit random codebook for QPSK modulation improves the performance as compared to that with the conventional scheme at the low E_b/N_0 region. |
